Got a machine in to fix, obviously an electrician using his spare parts to replace a missing leaf switch including a newly positioned rivet for the ball to run over in photo 2 

. 1st photo shows their repair and 3rd photo where the missing leaf switch is normally fitted to right of our hole.
Great use of mains flex and a mains power plug pin, ingenious
Needless to say now has a proper leaf switch again
